Which Free Slots are Our Expert Team Loving Right Now?
The Casino.co.uk team are always on the lookout for the latest free slots, to see which are worthy of our recommendation to UK players. Here are some recently released demo slots that have firmly earned our seal of approval:
Jon Young, Slots Expert: “I’ve been a big fan of the cute and colourful Reactoonz since the original slot came out in 2017, and the recently released Reactoonz 100 instantly caught my eye with its 10,000x max win (nearly double Reactoonz 2’s 5,083x). My favourite in-game feature is the Energized Toon bonus that boosts the payout on winning clusters by the current progressive multiplier, which has no upper limit.
It also has a lower minimum bet of 10p compared to 20p on the previous two games, making it more budget-friendly when I decide to give it a spin for real money.”
Martin Booth, iGaming Expert: “A personal favourite at the moment is Gonzo’s Quest II, which was finally released in September 2025 over a decade after the original by NetEnt. The familiar adventure theme set in the South American jungle initially made me feel nostalgic, but I was quickly distracted by the upgraded ‘avalanche’ feature. This adds up to 4 rows to the reels when you land successive wins and is a perk I couldn’t take advantage of in the original.
That means the game has a maximum of 262,144 paylines, which is even more than some of my preferred Megaways slots such as White Rabbit Megaways and Madame Destiny Megaways.”
Alan Kendall, Casinos Expert: “I’m always on the lookout for slots with niche mechanics, so I knew instantly I’d have to give the apocalyptic-themed xWays Hoarder 2 a try. Apart from the unique xWays feature that can transform reels to all have the same symbol, it keeps me excited with the four-level Raid free spins mini game, that removes low-value symbols and increases the number of available xWays as I progress.
Typically for releases from Nolimit City, it also offers a massive top prize (25,920x), large number of paylines (729), and decent hit rate (21.5%). This comfortably beats Big Bass Splash, which is the most popular free slot at most casinos I play at, for all three.”
Why Free Slots are Worth a Spin
Modern online slots are constantly evolving, and now often feature an assortment of complex mechanics that include power-ups and prize wheels, multi-level multipliers and high-volatility mini games that transform the reels and offer extra ways to win.
Playing these in demo mode is the easiest way to learn how a slot behaves before risking your bankroll. You can see how often a slot pays out and its bonus rounds trigger, preview what to expect when special symbols land, and check if the overall theme, graphics and gameplay suit your style.
Similarly to other free casino games, you can also load demo slots instantly without needing to download any software or sign up at a casino. So, which type of free slots player are you?
Casual Slots Enthusiasts
Free slots allow you to focus on the action-packed gameplay, eye-catching graphics and immersive soundtracks they offer without the pressure of potentially losing cash. That makes them perfect if you like slots more for the entertainment than chances to win money, or you’re budget-conscious when it comes to online gambling. Even when you’re playing in demo mode, the anticipation of potentially triggering a bonus round and enjoying colourful themes ranging from alien planets to the Wild West can easily prove fun.
Bonus Hunters
If you regularly claim slots-focused casino bonuses such as free spins, you can play free slots as a test to simulate how they would work. Free gameplay lets you see how much cash you might win, in order to assess if the promo is worth your money and time. As an example, you could test MagicRed’s welcome bonus by playing the Fire Joker demo in batches of 100 spins and noting your average win from them, before deciding if you then want to claim the no wagering offer.
Feature Fans
Free slots allow you to explore and find fun titles in your preferred or a new niche. For instance, you may particularly enjoy a certain type like Megaways slots, or come across a mechanic you’re unfamiliar with involving xWays, cascading reels or Hold & Win. In both cases, you can utilise free slots to better understand how they work and note data and stats that can inform your real money gameplay. An example could be how many spins are needed on average to trigger PopWins on Piggy Pop Grand Affair, or Gigablox on Lucky Ryan Gigablox.
Mobile Players
An estimated two-thirds of slots gamblers in the UK now prefer to play mobile slots, which is unsurprising given the added convenience of being able to enjoy your favourite games anytime, anywhere. Mobile free slots allow you to try out games on casino apps, so you can take advantage of high-quality graphics, smooth gameplay and fun features across thousands of games on your smartphone. Plus, if a casino offers an exclusive mobile bonus for a certain slot, you can get a feel for it beforehand.
Jon Young, Slots Expert: “A big reason why I like playing free slots is that they let me still enjoy classic games that are increasingly hard to come by at casino sites. Given my interest in the history of slots, one of my all-time favourites is Cash Splash, which was one of the first online slots ever released back in 1998.
However, it isn’t available even at my go-to casinos for large games libraries such as Coral and LeoVegas, so the demo at least allows me to revisit it when the mood strikes.”
Play 3,700+ Free Slot Games at Casumo
Casumo is home to a massive collection of nearly 4,000 free slots, which is more than triple the entire games collection at some of our top 5 UK casinos including Jackpot City and Betway. Highlights include 205+ Megaways titles including recent releases Wolf Legend Gold Megaways and Zombie School Megaways, plus long-standing favourites like Cleopatra and Eye of Horus.
As the library features titles from over 105 software providers (quadruple the number at Luna Casino), you can also try hundreds of releases from the likes of Pragmatic Play (415+), Play’n GO (345+) and Hacksaw Gaming (115+), all without spending a penny. The free play options extend to Casumo’s mobile app, which is rated 4.1 stars on iPhone and has over 100,000 downloads on Android.
Jon Young, Slots Expert: “I always advise it’s best to try high RTP slots for free, so then you can maximise your expected returns if you fancy playing for real money. Casumo lets me do just that by offering demos for Mega Joker (99% RTP), Pixies of the Forest II (98.83%) and Cash Stax (98.14%), all of which I could also easily find thanks to the helpful search tools.”
Player Review – Michael Hayward (Trustpilot): “From gameplay to quick withdrawals and fast customer support, the only reason I have given Casumo five stars is because I can't give six!”
Enjoy thousands of free slots at CasumoWhich Slots Can’t You Play for Free?
UK players can try any online slot game for free, provided the software provider that produced it has released a demo version. The most common slot type that has free versions with notable features removed and often restrict you to the base game are progressive jackpot slots.
This is because the games are designed to prevent you from winning the live jackpots when you’re not actually playing for real money. As an example, when we loaded the free demo for Age of the Gods, we couldn’t trigger the coin pick bonus round to win one of the four progressive jackpots and the real-time prizes were listed as “not available”.
Hit the Reels With Our Step-by-Step Guide
Found a free online slot you want to try? Here’s what to do once you’ve come across a demo you’re keen to give a spin and how to guarantee this proves useful:
Load the free slot: Before you do this, you may have to complete any necessary age verification checks.
Check the paytable: When the slot is ready to play, select the help section, as it has useful information covering paylines, RTP, volatility, the value of each symbol and max win, and how the in-game features and bonuses work. This will ensure you know exactly what to expect and can understand what’s happening on the reels.
Set your bet amount: To fully utilise free demo slots, we recommend playing with the virtual currency as if it was your own cash. This helps to gauge how many spins your bankroll would last for if you’ve deposited your standard amount, and practice reacting to streaks of winning or losing spins.
Hit the spin button: On most free slots, this is a circular button underneath the reels that says ‘Spin’ or has a 🔄 pattern. Alternatively, many free slots have an Autoplay function that lets the game run by itself for a specified number of spins.
See if you win: You’ll get a virtual payout when you wager results in a winning spin.
Be Ready to Prove Your Age
Since a July 2019 ruling by the Gambling Commission (UKGC), you need to be aged 18 or older to play free slots. Depending on what type of platform you’re using, proving your age involves the following:
- Online casinos: After creating an account, you’ll be asked to complete Know Your Customer (KYC) checks in order to prove your age (alongside your identity and address). This involves submitting documents such as your ID, passport or driving licence, and at most top casinos, these are normally approved within a few days.
- Other websites (e.g. software providers): Other sites hosting free games often use third-party tools, such as AgeChecked. These get you to enter your personal, electoral roll, or debit/credit card details in order to verify your age, which generally only takes a couple of minutes.
Expert Tips and Tricks to Get the Most From Free Slots
You can’t win real money spinning free online slots, but they can easily inform and benefit your gameplay when you do play for cash. Here’s our advice on how to get maximum value from slots demos:
🆕 Beat the crowd by trying upcoming slots
Software providers often provide demos for slots before the release date for the real money version, so you can check it out, determine if you like it, and get to grips with any new features before it’s even added to casino sites.
This can prove especially handy if your favourite casinos have a tendency to feature new slots in bonuses, so you immediately know if an offer represents good value for money.
🔎 Look out for free slots with high RTP and low volatility
If you want to practice on free slots that offer the best expected returns when you’re playing for cash, we suggest keeping an eye out for demos with a return to player (RTP) value above 98% and low volatility. These slots pay out more cash on average from £100 worth of bets than the £96 industry average, and are designed to provide smaller but more frequent prizes across your spins.
Examples include 1429 Uncharted Seas (98.60% RTP) and Royal Fruits 40 (97.71% RTP), but remember to check the RTP on the version you play at a casino, as sometimes operators host editions with a reduced payout rate compared to the demo. For instance, the RTP on Book of Dead can vary from 96.21% to as low as 84.18%.
🏆 Use free demo slots to practice for tournaments
You can utilise free slots to research your approach to slots leaderboards, particularly when you’re given a choice of games to play. Coral’s weekly free-to-enter Beat the Banker tournaments let you pick between 3 slots and award points for how many wins you land across 30 spins.
Before entering, you can play the featured slots for free to see if one stands out for its hit rate, or the size of its payouts if you’d prefer to try and earn extra points for bigger wins. This can potentially improve your odds of ranking high enough to get a reward.
🛡️ Gamble safely and responsibly when playing free slots
Free slots are no different to the real money versions in the respect that you should only play them at UK casinos licensed by the Gambling Commission (UKGC), to ensure that your money and personal data is protected by advanced security and encryption. In January 2025, the UKGC flagged that increasing numbers of unlicensed casinos were unlawfully hosting free slots from verified providers. We therefore suggest sticking to Casino.co.uk’s recommended casinos, which all have valid UKGC licences.
While we suggest using your time on free slots to get a feel for how real money gameplay might pan out, you also need to steer clear of using large virtual wins as encouragement to deposit and wager more money than your normal amount.
You can set deposit, wager and loss limits at casinos to prevent this, and access independent resources from organisations including GamCare, GambleAware and GAMSTOP if you’re concerned that playing free slots is contributing to problem gambling habits.
Expert Tip: When Should You Switch From Playing Free to Real Money Slots?
Jon Young, Slots Expert: “When I’m trying out a free slot, there are three main boxes I have to tick before I’m comfortable potentially wagering cash on my spins. Firstly, I aim to reach a level where I can confidently and quickly understand what has happened on each spin and why it did or didn’t pay out, without needing to refer to the paytable.
Secondly, I need to settle on a suitable bet amount for each spin, so I know how I want to use my bankroll when my money’s on the line. Lastly, I want a feel for how often the slot pays out and how many spins it generally takes to activate in-game bonuses and features. I normally a the free slot run on auto mode for 100 spins and keep a tally to help with the latter.”
Free Slots vs. Real Money Slots
Getting a feel for online slots via free demos has numerous benefits, but also drawbacks when compared to hitting the reels with actual cash. To ensure you’re up to speed on how both work, we’ve compiled the key pros and cons you should know:
| Free Slots | Real Money Slots |
|---|---|
| ✅ Offer a risk-free way to try a slot’s gameplay, mechanics, theme and more, so you can decide if you like it (and by extension, the overall slots collection at a casino) without potentially losing money | ✅ Give you the chance to win cash playing slots, most notably on progressive games with real-time jackpots that regularly reach over £1 million and can be triggered with a single spin |
| ✅ Allow you to preview upcoming slots from leading providers, so you already know if you enjoy them by the time they’re released | ✅ You can boost your bankroll while playing by taking advantage of slots bonuses such as free spins, deposit matches and cashback |
| ✅ Help you refine your wagering strategy for slots and give free spins bonuses a trial run by playing the demos of featured games | ✅ Still accommodate gamblers wanting to play with a small budget via no deposit offers and frequent free-to-enter slots tournaments |
| ✅ Let you play online slots without needing to sign up and complete KYC checks at casino sites and apps | ✅ Provide access to a larger selection of slots games, as not every real money title has a free demo available to play |
| ❌ You’re unable to win real money nor claim and use casino offers including free spins when playing free slots | ❌ Can only be played with cash, which can be quickly lost on unsuccessful spins given the fast-paced gameplay |
| ❌ Some slots such as progressive jackpots have certain features and bonus rounds removed from the demo | ❌ Require you to create, verify and fund an account at online casinos, which is more time-consuming than loading free slots |
| ❌ The RTP on a free slot game can be different to the version hosted at a casino, so it may give you a misleading experience as to how much the game pays out | ❌ Each casino hosts varying slots from different providers, so may you need to join several in order to play all your favourite free slots for real money |

Is playing free slots the same as getting free spins?
No, free slots offer demo versions of online slots games that you can play at any time and for any number of spins, but with the chance to land real money payouts removed.
By contrast, free spins are a type of casino offer that most commonly give you a certain number of bonus spins for depositing and/or wagering a specified amount, from which you can potentially win cash.
